APPARATUS FOR PRODUCING ORNAMENTAL BASH-BARS.

To all whom it may concern:

Be it known that I, VITARL HERMANN FRANZ HUTH, a subject of the King of Prussia, and resident of Hamburg, Germany, have invented a new and useful Improvement in Apparatus for Producing Ornamental Sash-Bars, of which the following is a specification.

Lead sash bars, which have an H-shaped cross section and are called by glaziers cames or turned lead are frequently used to connect panes of glass, for artificial glazing, fret-work, stained glass windows and the like. ornament sash bars of this description it was necessary to attach an ornamental strip .on the sash bar. Accordingto this invention these two articles are combined by cutting ornamental figurations on the flange of the sash bar, thus forming the bar into an ornamental sash bar itself- To carry out this part of the invention, supporting flat plates or the like preferably of the thickness of the, hollow spaceleft in the sash bar are introduced into the grooves and a rotating cutter is made to operate on one or both flanges, thus supported by the plate or the like, the sash bar together with the supporting plates, being held stationary and the cutter being rolled along the sash bar to cut out the desiredfiguration; or the rotate ing cutter may be journaled in stationary bearings and the bar together with the supports may be movable. If movable the supporting plates may be made in the shape.

of disks and provided with means to rotate the same.

In a preferable mode of construction two pairs of cutting disks are mounted on two shafts and intermediate of the same two supporting disks are ournaled in such manner that the sash bar is slipped on the same, and the cutting disks operate on the flange, when rotated. The cutting disks and sup porting disks are all driven from a common shaft, which may be rotated either by hand or mechanically. The shafts carrying the cutter disks are preferably adjustably j ournaled to allow for sash bars of different thickness.

In another mode of constructionthere is only one pair of cutting disks rotatably mounted in a tool similar to a carpenters partly project with a longitudinal edge into Specification of Letters Patent.

the grooves of the sash bar and thus support its upper flanges. Means are provided to tighten one rail against the other so as to firmly hold the bar between them, when at the. same time supporting its flanges.

Figure 1 of the drawings is a side view partly in section of the preferred construction ofan apparatus for producing ornamental sash bars. Fig. 2 is a plan and Fig. 3 a front View of the same apparatus. Fig. 4 is a side view of a simplified modification, Fig. 5 a plan and Fig. 6 a cross section of the same. Figs. 7 and 8 show ornamental sash bars made according to this invention.

The apparatus shown in Figs. 1 t0 8 comprises a frame a, which is preferably so shaped as to be adapted to be fastened to a table. Two shafts Z) and 0 are journaled in this frame, and are operatively connected by gear-wheels (Z and e of equal diameter and pitch of teeth. At one end of the upper shaft?) a conical wheel f is mounted, meshing with another conical Wheel 9, hereinafter more fully described, and the correspending end of the shaft 0 carries a head it. On the face of the head it and that of the conical, wheel f there is a groove 7; crossing the center of the shaft or disk, the purpose of which is hereinafter explained.

Contacting with the face of the wheel f there is a vertically sliding bracket is suitably guided within the frame, and below this bracket and arranged opposite to it there is a second sliding bracket k also guided in the frame and contacting with the face of the shaft-head h. In each bracket 72 and 78 a shaft m is journaled ap proximately in line with the shafts b and 0 respectively and, provided at one end with a head 7L having, similarly to the head in and to the conical wheel f at its outer face, a groove disposed centrally with regard to .the center line of the shaft. Between the heads k and h or wheel f respectively, there is a disk it provided at both its faces with a feather 0 fittingin the grooves 2' described above. On each disk 91. the feathers on opposite sides thereof are arranged at an angle of 90 to one another. Thus a coupling is constructed permitting the shafts m to be rotated by the shafts b and 0 though they are not perfectly in line. To raise and lower the brackets 70 and k adjusting screws 70 are provided.

On each shaft m there is a socket p attached, threaded on its outer surface and a washer 9 may be arranged. The disks 9 are annularly shaped to allow them to be slipped over the socket 79, and they are each provided with an inner projection, (not seen in the drawing) projectinginto one of a series of slots p in the socket, so as to prevent the cutting disks from rotating on the socket. By the aidof two nuts 1 the cutting disks 9 may be adjusted and firmly fastened on the socket. In a plane intermediate of the-two pairs of'cutting disks two 5 horizontal supports as disks 8 and-s ,are

journaled, the shafts s and s of which are 'operatively connected with one another by a train of' gearing 25,1 t 25 These two supporting disks have edges of the thickness of the grooves in the sash bar to be operated upon and are made of soft material such as vulcanite or fiber. The disk 5' may be detachably secured on its shaft or pivot pin .9 to enable it to be removed or loosened, for the sake ofcrepairs, or replacingof a disk of different thickness, or for better introducing the sash bar u, should any dificulty arise thereby. The shaft 8 carries the coni-.

cal wheel 9 mentioned above, to transmit rotation. when the shaft 5 is rotated. This shaft 5 has fixed and loose pulleys w and 10 to enable it to be driven by mechanical power, and the end a" of the shaft .7) is squared or otherwise adapted to be driven by hand by the aid of a hand crank or hand wheel not shown in the drawing that may be placed on the said squared end in a well known manner. Of course if desired only one of the driving means may be provided for. i

, From the foregoing it will be well understood that if a sash bar it is introduced in the manner as shown in Fig. 1 and the apparatus is set to wor: by rotating the shaft 5 the disks 8 and s will draw the sash .bar through the machine and the knives will cut the flanges of the turned lead or sash bar so as to give the edges the configuration incident to the shape of the cutting disks.

As a rule it will not be necessary to use both pairs of cutting disks. Frequently it will be required to have sash bar ornament-w tions only on one side of the window. In this case one pair of cutting disks preferably the lower ones will be removed. The apparatus will then turn out sash bars or namented only on one side, as is shown in Fig. 7. Even only one single cutter may be used, so as to produce a sash bar, of which only one of the four flanges is ornamentally cut out.

For enabling the, removing and replacing of the cutting disks, the front part 1 of the brackets 70 is not integral with the other parts but merely fastened by the aid of the known thumb screw e. The shafts m are journaled in a slot 3 opening out laterally are turned at an angle of 60 they will produce an ornamental bar such as shown "in Fig. 8.

'- The-thickness of sash bars varies; For

this or other jreasons'-the cutting disks may be adjusted as to height, which is done by lowering or raising 'the'brackets 7r, and'ic' as described above.

If sash bars are to be produced, that are ornamented only on one side as shown in Fig. 7, the apparatus shown in Figs. k6

may be used with advantage. o I

On a long block or board I suitahly' shaped are mounted the bar supports which consist of a rail 2 fastened on the board,

opposite second rail 3 which isdetachably g removed by unscrewing the .[f for instance in the machlne shown the right hand cutters or removably and adjustably arranged.

This rail 3 is fastened to a bar 4, which may be screwed or otherwlse pressedagalnst the projecting body of the block 1 for instance by the lever 5, so as to firmly holda sash-bar u on the rails 2' and 3. :On the device so far described an implement 6 similar toa carpenters plane is placed, consisting .Of a frame having 'a-back handle 7 and a l front handle8. Within this frame which has flanges 9 reaching over "the rails 52 and :8 a screwpinWlO' isfastened serving as an axle for a socket-ll;

This socket is constructed similar to the socketphereinbe'fore described, with cutting disks, fastening nuts and a washer.

It will be well understood that if the implement ,6 is gripped by the hands similar to a carpenters plane and moved along the rails 2 and 3, the cutting disks can be rolled along the sash bar and will give the upper flanges the desired ornamentation. 'It is evident that also in this apparatus only one cutting disk may be used if desired.

It need scarcely be pointed out that the two examples illustrated and described above yb p a ed by apparatus of vari ous constructions tocarry out. the present invention.
